Purpose: Safety of humans is an important factor that affects health overall, and injuries are one of the major public-health problems in the world. The purposes of this study were to describe the International safe Community movement which contributes to the injury prevention and safety promotion all over the world, and to identify out the application and developmental strategies for Korea. Methods: A review was done of previous research, reviews, and reports on the history, concepts, basic principles, and recommendations for actions of the Safe Community. Results: For this study, the application strategies of the International Safe Community movement in Korea were examined to deduce the strengths of the safe Community program. Community-based injury prevention work according to the International Safe Community model is a successful and cost-effective way of reducing injuries in the community. Conclusion: Through the International Safe Community program, communities are able to realize a healthy community and achieve improved quality of lives for the people, which is the ultimate objective of the Safe Community model. In addition, it will contribute to the economic vitalization and gain through energy and enhancement of productivity of people.

Nozzle in nuclear power plant is connected to pipe using safe end. Dissimilar metal weld between nozzle and safe end is followed by similar metal weld between safe end and pipe. And thus residual stress in dissimilar metal weld can be affected by similar metal weld. Similar metal weld impose bending stress on dissimilar metal weld, which is according to the length of safe end. In this study, simple nozzle model which covers various radius to thickness ratios was proposed to quantify residual stress in dissimilar metal weld based on finite element analyses. As a result, short length of safe end was proved to be more effective to mitigate residual stress in dissimilar metal weld and critical effective length of safe end is provided according to the radius to thickness ratio.

Feed safety is needed to produce and provide safe animal feeds for consumers, animals, and the environment. Although feed safety regulations have been set for each country, there is a lack of clear feed safety regulations for each livestock. Feed safety regulations are mainly focused on heavy metals, mycotoxins, and pesticides. Each country has different safe levels of hazardous materials in diets. Safe levels of hazardous materials in diets are mostly set for mixed diets of general livestock. Although there is a difference in the metabolism of toxic materials among animals, the safe level of feed is not specific for individual animals. Therefore, standardized animal testing methods and toxicity studies for each animal are needed to determine the correct safe and toxic levels of hazardous materials in diets. If this goal is achieved, it will be possible to improve livestock productivity, health, and product safety by establishing appropriate feed safety regulations. It will also provide an opportunity to secure consumer confidence in feed and livestock products. Therefore, it is necessary to establish a scientific feed safety evaluation system suitable for each country's environment. The chance of outbreaks of new hazardous materials is increasing. Thus, to set up appropriate toxic levels or safe levels in feed, various toxicity methods have been used to determine toxic levels of hazardous materials for humans and animals. Appropriate toxic testing methods should be developed and used to accurately set up and identify toxicity and safe levels in food and feed.

Purpose: In this descriptive study, we aimed to identify factors influencing safe nursing activities of nurses working at public hospitals. Methods: We collected data in March 2021 through an online survey. The subjects were 199 nurses who had worked for at least six months at public hospitals. The self-reported questionnaire consisted of items pertaining to safe nursing activities, perception of patient safety culture, and the general characteristics of the subjects. To examine the differences in the safe nursing activities and perception of patient safety culture by general characteristics, we employed a t-test and ANOVA. We conducted a multiple linear regression analysis to explore the factors affecting safe nursing activities. Results: The mean score for safe nursing activity was 4.59±0.39. Perception of patient safety culture and age group were found to be the main factors affecting the safe nursing activities of nurses working at public hospitals (F=17.24, p<.001, Adj. R²=.40). When the score for perception of patient safety culture increased by 1 point, the score for safe nursing activities increased by 0.58 points. In addition, the score for safe nursing activity in the 40s age group was 0.16 points higher than for those in the 20s age group. Conclusion: Effective management and leadership in public hospitals is needed to improve the culture of patient safety at various levels so as to ensure safe nursing activities.

본 논문의 안전운행 보상시스템은 안전운전을 수행한 차량운전자에게 직접적인 보상을 제공하여 안전운전의 동기를 부여하고 적극적 참여를 유도함으로써 사고의 발생을 줄여 생명과 재산의 손실을 줄이는데 목표가 있다. 기존의 디지털 운행기록계의 경우 차량의 운전상태를 기록만 하였으나, 안전운전보상시스템은 사고예방 효과를 높이기 위한 지원책으로서 안전운전을 수행한 경우 금전적 보상을 통해 위험운전을 피하고 안전운전을 하도록 유도하였다. 즉, 과속으로 인한 사고 발생 빈도가 높은 지역에서는 속도 준수, 또는 차 간 거리 유지, 지정차로 운행 등의 안전운행 지시를 수행한 경우 직접적인 보상을 제공함으로써 안전운전 동기를 부여하여 교통사고를 예방하고자 한다. 이러한 안전운행 데이터와 보상내용은 투명하고 안전하게 관리되어야 하므로 보상근거와 보상내용을 폐쇄형 블록체인 하이퍼레저 패브릭을 이용하여 구축하였다. 그러나 블록체인 시스템은 투명성과 안전성이 보장되는 반면에 낮은 데이터 처리속도가 문제가 되므로 이를 개선하고자 블록생성 가속 기능을 구현하였다. 본 연구에서는 순차적으로 블록을 생성하는 속도가 10TPS(Transaction per second) 내외의 낮은 속도를 나타내어, 블록의 생성속도를 높이기 위해 가속 기능을 적용한 결과 1,000TPS 이상의 고성능 네트워크를 구현하였다.
